An illuminating device includes: an upper substrate and a lower substrate facing each other and spaced apart from each other; an anode electrode arranged on a lower surface of the upper substrate; a phosphor layer arranged on a lower surface of the anode electrode; a cathode electrode arranged on an upper surface of the lower substrate; an electron emission source arranged on the cathode electrode; and a reflection film arranged between the electron emission source and the phosphor layer and respectively separated therefrom, the reflection film being patterned on a surface facing the phosphor layer to diffuse light emitted from the phosphor layer. The illuminating device provides improved brightness uniformity by forming a pattern on the reflection film so that light can be uniformly diffused or dispersed.
